The object of this Code is to provide a test procedure to determine the thermodynamic performance of an axial or centrifugal compressor doing work on a gas of known or measurable properties under specified conditions. This Code is written to provide a test procedure, which will yield the highest level of accuracy consistent with the best engineering knowledge and practice currently available. Nonetheless, no single universal value of the uncertainty is, or should be, expected to apply to every test. The uncertainty associated with any individual ASME PTC 10 test will depend on practical choices made in terms of instrumentation and methodology. Rules are provided to estimate the uncertainty for individual tests.
This Code covers a defined range of primary fuel characteristics, but is limited to combined-cycle, power generation systems using gas and steam turbines. This Code defines the boundaries of the overall IGCC power plant to encompass three major plant sections - the air separation unit (ASU, for oxygen-blown gasifiers or plants that use nitrogen), the gasification process (including gas cleanup), and the power block. Tests conducted by this Code determine the quantity and quality of fuel gas by its flow, temperature, pressure, composition, heating value, and its content of contaminants. Contaminants are compounds that are potentially deleterious to the gas turbine and power block in general, or are precursors to stack emissions. Contaminants to be measured are sodium (Na), potassium (K), vanadium (V), lead (Pb), calcium (Ca), barium (Ba), manganese (Mn), phosphorus (P), sulfur compounds (H2S and COS), nitrogen compounds (HCN and NH3), chlorine compounds (HCl), and particulate matter. Recommendations are included for the following in pretest agreements: testing procedures, types of instruments, methods of measurement, methods of calculation, and contents of test reports. Regulatory compliance testing of IGCC power plants is not covered by this Code.
